The theological virtues of faith, hope, and love (1 Cor. 13:13) characterize the kind of soul that is in perfect fellowship with both God and neighbor. The cardinal virtues of prudence, justice, fortitude, and temperance are a blueprint for the kind of soul without which a good society would not be possible. They originate as the four essential virtues from Plato’s Republic Book IV and were expanded upon by Cicero, Augustine, and Aquinas in subsequent centuries.
